Just after the battering-ram room, Blue exclaims "If the cops are?", I wasn't really sure what he was alluding to.
During/after the Penguin's courting ritual, the line was "Damn those penguins getting all love dovey!", I think it should have read, "Damn those penguins getting all LOVEY dovey!"
Now, my short term memory isn't what it used to be... As far as i can recall, there's a scene with a cat playing with some yarn, the line reads, "He's playing like some yarn", I think it should have read, "He's playing with some yarn." -- Really sorry for not remembering the specific scenario, I think that might have been a late session that night
And the last one I spotted was just after opening the large Green Door and encountering the Patchies, they exclaim, "We there was treasure in here so we came in, but then the door closed and we were trapped!", I presume the line was supposed to read, "We thought there was treasure" or, "We knew there was treasure in here..."
Like I said, besides these few minor phrases, the script was a joy to read and the game a joy to play through as a result, can't wait to see the finished patch!
